Well the outfit I work for is sending me out of town leaving 03-07 I ordered a G2 from Big Boy's and already have an AT Pro I grew up around my Dad's Garrett discriminator and so when it came time to buy one for myself I bought the GTI 2500 don't know if it was me or the machine but I never cared for it I bought the AT Pro then sold the GTI 2500 to finance the G2. I already have permission to hunt an old farm 10 miles north of Trenton, MO. where I'll be working and am thankful the structures are still standing the areas I normally get to hunt are foundations only and I believe they filled the house's to the rafters with nails and then dismantled them with a bomb slinging nails by the thousands in all directions. So I'll be taking both machines with me and see how they do side by side. Good luck to me and I'll talk to you all when I get back in a few weeks.
